I did terrible in High School but I’m trying to make up for it in college. As of now I go to my local CC and I’m doing great. As of now I have a 4.0 GPA and I’m involved in several clubs. I want to apply once I meet the 27 credit threshold but would I have a chance of getting in?

I don't think that your HS GPA will hurt you much, if at all. You've clearly grown since HS, have a good head on your shoulders, and will just have to show that you can hack it at ND. In summary, you're not screwed.

I have had quite a few friends that have done this as well and most conversations went like this:
1. Great job on your successes and improvement from hs, we’d love to have you join our school.
2. We’d like to see a longer demonstration of your successes after high school, compete your 2year degree and we’d love to have you join our school.

Might not be what you want to hear, but it isn’t impossible. Just ask and be ready to sell yourself as a teachable and growing young adult ready to join the ND legacy.
